The perform of 135m finishing mill group
The ending mill group is composed of leading crossed 45° Higher-speed wire-rod ending mills&interval
The finishing mill group is positioned in high-speed wire-rod workshop&period of time Through ten device rack the steady micro-stress rolling mill will be transported upstream Æ 17 ~ Æ 21mm of rolling&comma rolling turn out to be Æ 5&period5 ~ Æ 16mm concluded wire&interval The functioning pace of 90m&sols is insured&period The specification of stop item is Æ 5&period5mm&period of time

Structural qualities of finishing mill
Ending mill unit is mixed with 10 mills&comma velocity increasing box&comma help foundation&comma arc coupling&comma watertight slot&comma waterproof plate&comma the protective include&comma piping and information of finishing mill&time period Mill body is composed of 3 200mil EPT and 7 one hundred fifty mills&comma frame use leading crossed 45 composition kind to attain no twisting&comma no make contact with axis&comma small axis and shock for tools&comma aside from&comma it lessen the center of gravity height&comma the steadiness improved as nicely&comma in the imply time&comma the complete weigh has lower and it is straightforward to preserve&time period 10 frames are concentrated transmission&time period
Roll body is composed of roller box&comma bevel gearbox and spare parts of bevel gearbox&time period
Roller box and bevel gearbox adopt outdoors combinational instruction&comma reduce the dimensions of bevel gearbox to decrease the weight of finishing mill&comma lower the room of mil EPT to make their framework compact&period of time Roller box utilized cantilever roll loop&comma there is eccentric locking collar in the box to adju EPT roll gap&period Movie bearing and roll shaft are within eccentric locking collar&comma taper sleeve is employed to resolve roll loop which is in the conclude of roll shaft&interval
Bevel gearbox is composed of box&comma transmission box&comma spiral bevel equipment roll and synchronized gears&period All gears are hardened grinding equipment&comma geartooth correction is necessary&time period The accuracy degree of spiral bevel gearbox is 6 and round bevel gearbox is five to insure the smooth working of large velocity&time period
Roller box and bevel gearbox are related by bolts&comma a part of roller box plug into the bevel gearbox to let two synchronized gears in bevel gearbox meshed&time period Roller box and bevel gearbox are mounted by two finding pin&comma the roller box with exact same specification can be changed&interval
The axial drive of the roll shaft beared by a pair of thru EPT ball bearings&comma this ball bearing mounted on the axial clearance in the absence of the resilient washer&comma simply because the very modest axial clearance ball alone&comma as a result the roll shaft to accurately positioned in the axial direction&comma which makes certain exact roll rolling precision&comma which is to guarantee the dimensional precision of the workpiece&period of time
The roller shaft in close proximity to the film bearing is developed in the form with taper&comma so the roller shaft can bear uniform load distribution even it is bend&time period So the life time of roller can be improved&period
The adjustment of roll hole is to rotate feed screw with still left and right thread and nut&period When the two eccentric rotated relatively&comma the length of two rollers changed with the symmetrical eccentric relative motion of eccentric locking collar&comma so the location of former roller line and guide can be maintain&period of time
Roller loop is tungsten carbide&comma it is related on the cantilever roll shaft&comma we use the certain hydraulic shifting roll gear to change roll loop&comma it is practical and simple&interval
